REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol

<< < (273/566) > >>

Carrington:
How many hardware versions are up to date?

And now that I've bought a DS2072 if it appears that also has a hardware fault then ...  :o :rant: |O

 ::) I hardly think it's the end of the world. My Tektronix analog scope doesn't even have coupling choices for the trigger - and I can't say I've ever used AC-coupling for the trigger on a DSO yet.

Carrington:
Yes you're right, "I hardly think it's the end of the world."

Only I wish it was not a hardware failure.
If it is, do not want to jinx myself, but lately everything goes wrong.
Let us trust in the experience Rigol.

I've been using my DS2000 happily for over 8 months with absolutely zero regrets and only minor problems.

Carrington:
Anyone have an image of the input stage of a DS2072?
To compare with this (DS2202):

SMD Marking:
  6U -> MMBFJ309, N-Chanel RF Amplifier.
  3E -> MMBTH10, NPN RF.
  1B -> BC846, NPN.
  JY ->  BAV199, low leakage double diode.
  B7A -> AD8510

Would be very interesting see the frequency response until the input of the LMH6518. And a schematic of the entire input stage would also be great.



If there are "common desing HW" (inherited) between the DS2072 and DS1052E, then I want to believe that this failure is not due to hardware.  :)
